Yankees' Ivan Rodriguez out with injury

UPDATE: The Yankees say Rodriguez has a bruised right knee. The team said no further tests are required and he is day-to-day.

The Yankees removed catcher Ivan Rodriguez from tonight's game after a home-plate collision with Texas' David Murphy.

Both Rodriguez and Murphy collapsed to the ground after Murphy was out trying to score from second on a single to right, ending the bottom of the second inning. It was not immediately clear what Rodriguez's injury was, but he was pinch hit for in the top of the third.

The Yankees acquired the 14-time All-Star from the Detroit Tigers on July 30, and in six games for the Yankees had batted .214 (3-for-14).
